To all whom it may concern: I ets d for the struts which are shaped to give Be it known that I, HENRY E. HADDOCK, I a fiat bearing for the nuts or heads of the a citizen of the United States, residing in rod. These brackets are mounted between Cleveland, Ohio, have invented certain Imthe flanges of the lower channel beam f provements in Knees for Car-Platforms, of forming the lower cord and are secured by WhICll the following is a specification. rivets or other means. This construction of The ob ect of my invention is to improve t platform knee is very light and yet substanthe construction of the knees which support tial, readily carrying the weight of the ex.- the platform of a passenger car, particutended platform and will not drop. One of larly of the type having an extended platthe objections to a platform knee made of form such as cars in which the passenger I lumber is that it will shrink; after it is pays the fare on entering the car and where placed in position. space is desired for the free ingress and .1 preferably mount in each of the egress of assengers, although it will be un 5 channel bars a wooden sill E. This sill derstood t at my invention can be used with is secured to .the channel bar by advantage in cars of other types. illustrated in Fig. 2, and mounted on these In the accompanying drawing r-Figure sills are boards forming the floor of the platform. I preferably mount on each side of the center These knees extend from the end sill a and the bumper or crown piece b. Angle braces g, g extend from the knee D at the sill a to the center of the crown piece, as illustrated in Fig. 2, bracing the platform against any lateral movemen By the above construction I make a very light and substantial platform kne'e which cannot shrink and therefore the platform will not sag, as is the case in most platforms in which the knees are made of lumber.

I claim 1. The combination in a knee for a car platform having upper and lower cords, with struts of different lengths, and a tension rod extending from a point some dis tance from the center strut at the lower cord and extending over the center strut.

2. The combination of a car body having an end sill, a platform knee made up of upper and lower cords, struts spacing the form knee; Fig. 2, is a side view of my 1mproved platform knee with sufficient of the to illustrate its application; Fig. 3, is a plan view; Fig. 4, is a viewof a detail; and Fig. 5, is a transverse sectional view on the hue 55, Fig. 2 A is the lower frame having an end sill a and side sills a of the ordinary type.

B-is the platform having'a wooden floor b, and b is the bumperor crown piece of the platform. I

D, D are the two platform knees, one arran ed in the present instance at each side e car body and projecting from the, end thereof and acting as the supports for the platform B. The two knees are made of metal; the upper cord E is a channel bar with the flanges turned upward and the lower cord F is another channel bar with the flanges turned downward. These two channel members areunited at each end by riveting or welding and struts C, C and C are laced at intervals throughout the length l of t e knee so as to space the upper and lower cords the proper distance apart. The upper cord is bent at a so as to allowthe overhanging portion of the knee to drop sufficiently below the end sill a of the car body, I so 'as to bring the platform to the proper level. d is the tenslon rod extending from a point under the strut c to a point under the strut c and this rod extends through the top of the central strut'C. The rod has nuts at each end so that it can be taken up at instance I form brackstrut being higher than being under the silltof the car, that portion of the knee extending under the car body being secured to the side sills, the other end of the knee extending to and supporting the crown piece of the platform, as well as, the floor of the platform.

3. The combination in a car, of a body portion, two knees one at each side of the car and projecting support the platform, the knees being made of two longitudinal channel bars forming bolts, as
